The correct answer is D. Velocity and return on assets (ROA) is the most desirable measure of supply chain performance from a stockholder perspective. Velocity refers to the speed at which products move through the supply chain, which is important for meeting customer demand and reducing inventory costs. ROA measures the profitability of a company's assets, which is important for stockholders who are looking for a return on their investment. By improving velocity and ROA, a company can increase revenue and profitability, which is beneficial for stockholders.
Option A, diversity of sales channels, may be important for overall business success, but it does not directly relate to supply chain performance.
Option B, lean manufacturing performance, is also important for supply chain efficiency, but it does not necessarily translate to increased profitability or return on assets.
Option C, time to market of new products, is important for gaining a competitive advantage, but it does not directly relate to supply chain performance or stockholder perspective.
